Over 230 people have been confirmed dead while 288 sustained injuries following a terrorist attack at a busy inter-section in the Somali capital, Mogadishu, on Saturday, a lawmaker said on Sunday.

First deputy speaker of the Upper House of the Somali parliament, Abshir Mohamed Ahmed, confirmed the latest casualty figures to reporters, saying emergency assistance for the injured has been intensified.

"Myself and other members of the Upper house of Somalia Parliament attended the funeral of several people who died in yesterday's deadly incident in Mogadishu," said Abshir. "We visited both Madina and a Turkish-run hospital and gathered from medical officers that 230 dead bodies were admitted there."

Mogadishu residents on Sunday came out in large numbers to donate blood to help save the lives of injured victims.

The special representative of the chairperson of the African Union Commission for Somalia, ambassador Francisco Madeira, urged collective resolve by Somali people and their allies to defeat terrorism.

"It is this strength and resilience of the great people of Somalia that will contain and defeat Al-Shabaab and continue to pave the way for the rebuilding of the country," said Madeira.

"We should together transform this tragic attack into renewed strength and resolve to continue working to restore peace and stability in Somalia," he added.
